Nothing reaches five inches

On this page11
A hard ceiling. And it is an outside measurement, so the opening is narrower.

Diameters are recorded for 220 of the 251 containers

Thirty one rows record none. For the rest the widest figure anywhere on this shelf is 4.625 inches.

Which means there is a ceiling, and it is worth stating plainly

No container on this shelf has a diameter of five inches. Not a narrow selection, not a handful: none.

And the approach to the ceiling is steep

189 rows reach two inches, 74 reach three, 54 reach 3.5, 7 reach four and 5 reach 4.5. The last inch of the range holds seven rows.

So three inches is the practical wide end

Seventy four rows, which is a real selection. Above that the shelf is down to two figures and then to single figures, and a specification written at four inches has almost nothing to resolve to.

A five inch embroidery hoop will not lie flat in anything here

Which is a statement about this shelf and not a criticism of it. The shelf is a small container shelf and a hoop is not a small part.

Hoop hardware is a different matter and it fits easily

The screw, wing nut, bracket and band are short. They need floor area rather than diameter, and 74 rows at three inches or more provide it.

The figure is an outside diameter, so the opening is smaller again

An outside diameter includes the wall. The neck finish is the number that describes the opening, and on this shelf the two widest finishes are 70-400 and 89-400 with 56 rows each.

Those two account for 112 of 251 containers between them

So the wide mouth end of this shelf is well supplied in closure terms even though the outside diameter tops out below five inches. The mouth and the body are two separate questions.

Nineteen rows record no neck finish and thirty one record no diameter

Which overlap only partly. For a shape sensitive job the practical effect is that a meaningful slice of the shelf cannot be screened on the dimension that matters, and has to be checked individually.

The surface area theme in the rule above is a coincidence worth noting

Part 303 measures a decoration as a fraction of an article’s surface area, which is a two dimensional measure. This shelf is also limited in two dimensions rather than by volume. The two facts are unrelated and the habit of thinking in area rather than amount serves both.

References

The Davis Pack Supply catalog, measured 19 October 2026. Of the 220 containers that record a diameter, 189 reach two inches, 74 reach three, 54 reach 3.5, 7 reach four and 5 reach 4.5. None reaches five inches. The widest on the shelf measures 4.625 inches. The flattest rows are polypropylene round tubs at 1.5 by 4.5 inches, a ratio of 0.33, and a 7.4 mL polypropylene hinged container at 0.5 by 1.5 inches. These are outside dimensions, so the opening is narrower than the figure given.
16 CFR 303.12(a), which exempts trimmings incorporated in wearing apparel and household textile articles "except for decorative trim, decorative patterns and designs, and elastic materials in findings exceeding the surface area thresholds", lists at (a)(2) "Decorative trim, whether applied by embroidery, overlay, applique, or attachment", and provides that such trim or design "does not exceed 15 percent of the surface area of the household textile article". Where no representation is made and the content differs, "the fiber content designation of the basic fabric shall be followed by the statement “exclusive of decoration.”" Paragraph (b) allows elastic material up to "20 percent of the surface area", followed by "exclusive of elastic." law.cornell.edu
Written from 16 CFR part 303 and from the catalog as it stood on 19 October 2026. Part 303 implements the Textile Fiber Products Identification Act and governs fiber content labeling on finished textile products; it does not govern floss, needles, beads or hoop hardware, and nothing here says it does. Heights and diameters in the catalog are outside dimensions, so no interior measurement is stated on these pages. This shelf is shared identically by nine groups and the sewing notions property enumerates the inventory.
